[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 shown, a sofa fabric includes a surface layer 1, a first insulating layer 2, a heating layer 3, a second insulating layer 4, a reflective layer 5, and a bottom layer 6 from top to bottom.

[0023] Among them, the surface layer 1 is artificial leather. Specifically, the artificial leather includes a base cloth and a polyurethane coating attached to the base cloth. The base cloth is woven from the second composite yarn.

[0024] As Figure 3 shown, the second composite yarn includes a core filament and a wrapping filament helically wound around the outside of the core filament. The core filament is spandex filament 14. The wrapping filament includes ramie fiber yarn 13 and polyester filament 12. The ramie fiber yarn 13 is helically wound around the outside of the spandex filament 14 to form an inner coating layer, and the polyester filament 12 is helically wound around the outside of the ramie fiber yarn 13 to form an outer coating layer. The ramie fiber yarn 13 has good antibacterial and mildew-proof properties, which can prevent the sofa fabric from growing bacteria and mildew. Among them, the polyester filament 12 is preferably a far-infrared polyester filament, which has the function of absorbing and releasing heat and can improve the functionality of the sofa fabric.

[0025] The first insulating layer 2 is woven from nylon filaments. Preferably, the nylon filaments are antibacterial nylon filaments to improve the antibacterial performance of the sofa fabric and avoid the growth of bacteria.

[0026] The heating layer 3 is formed by the interweaving of warp yarns and weft yarns. The warp yarns are made of polyester filaments, and the weft yarns are made of carbon fiber heating filaments. Both ends of the carbon fiber heating filament are connected with power supply connecting wires, and one end of the power supply connecting wire is exposed outside the fabric for connecting to a power supply. After the carbon fiber heating filament is energized, it generates heat, enabling the sofa to have self-heating performance and overcoming the problem that the surface of the sofa is cold and uncomfortable in a low-temperature environment. The electrical connection and its connecting components are conventional existing technologies, and will not be elaborated in this application.

[0027] The second insulating layer 4 is woven from nylon filaments. Preferably, the nylon filaments are antibacterial nylon filaments to improve the antibacterial performance of the sofa fabric and avoid the growth of bacteria.

[0028] The reflective layer 5 is an aluminum foil cloth, which mainly plays the role of reflecting heat and far-infrared rays, so as to achieve the purposes of energy conservation, heat preservation, improving the utilization efficiency of heat, and rapid heating.

[0029] The bottom layer 6 is woven from the first composite yarn, as Figure 2 shown, the first composite yarn is formed by twisting and plying nylon filament 11, polyester filament 12 and ramie fiber yarn 13. The nylon filament 11 and the polyester filament 12 have high strength and high anti-deformation ability to meet the use requirements of the sofa fabric; the ramie fiber yarn 13 has antibacterial and mildew-proof ability, which can improve the antibacterial and mildew-proof ability of the sofa fabric.

[0030] Furthermore, a silica gel layer 7 is provided between the surface layer 1 and the first insulating layer 2. A temperature sensor is provided on the silica gel layer 7, and the temperature sensor is connected to an external device through an electric wire. The silica gel layer 7 can protect the temperature sensor and also improve the flexibility and elasticity of the sofa fabric. The temperature sensor is used to detect the heating temperature and send the temperature signal to an external control device through the electric wire. The control device controls the operation of the heating filament according to the temperature signal to avoid danger caused by too high temperature.

[0031] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field according to the concept of the present utility model through logical analysis, reasoning or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
